as a nutritious fodder deserves more attention than it receives. The 

 tops serve as a substitute for spinage [Dr. M. T. Masters]. It is 

 also important for green manure, particularly when nitrogenous 

 aliment is needed for culture-plants. The green fruit contains 

 inosit-sugar and cholestrin-fat. For field-culture a sandy-calcareous 

 loam should be chosen for this plant, to insure rich and safe harvests. 

 Peas retained their vitality after four years' exposure to the extreme 

 frosts of Polaris-Bay. P. Aucheri (eTaubert and Spach), which is 

 perennial, occurs in alpine elevations on the Taurus. 



Pittosporum bicolor, Hooker. 



Tasmania and Victoria, ascending to 4-5,000 feet. This tree will 

 resist considerable frost. 



Pittosporum phillyroides, De Candolle. 



Continental Australia, in desert-regions. A small tree with 

 weeping branches, therefore adapted for planting at groves in 

 countries without severe winters. Pervaded by a medicinal very 

 bitter principle. Flowers very fragrant. 



Pittosporum tenuifolium, Banks and Solander. 



New Zealand. This with P. eugenioides (Cunningham) has 

 proved very suitable for tall garden-hedges, for which these and 

 several other species were first brought into practical notice by the 

 writer ; they are always clean-looking ; the foliage is well suited 

 for the surrounding part of table-bouquets. Unhurt by a cold of 

 9 F. [Gorlie]. Hardy at Campbelltown, Argyleshire. Better 

 resisting the frosts in the most southern parts of New Zealand than 

 any other indigenous species [T. Waugh], thus fit for shelterless 

 culture in South-England. P. Ralphii (Kirk), also from New 

 Zealand, endures the winters of Arran. Seeds of any Pittosporum 

 hardly ever fail to germinate ; they also keep well. 



Pittosporum undulatum, Ventenat. 



South-Eastern Australia. This tree produces a wood well adapted 

 for turners' purposes ; to some extent it serves also as a substitute 

 for boxwood. The flowers furnish a highly fragrant volatile oil on 

 distillation. The tree under very favorable circumstances attains a 

 height of 80 feet ; it is largely pervaded by a bitter peculiar principle, 

 which occurs also in other species. Quite fit for shade-lines where 

 celerity of growth is not an object. 



Planera aquatica, Gmelin. 



South-Eastern States of North America. An elm-like tree, 

 which can be chosen for plantations in wet localities. The wood 

 is hard and strong.
